ADVANCE INFORMATION January 20, 2012 Low Power Multi-Rate Quad Channel Retimer General Description Features The DS110RT410/DS110DF410 is a four-channel multi-rate retimer with integrated signal conditioning. Both the DS110RT410 and the DS110DF410 include an input Continuous-Time Linear Equalizer (CTLE) on each channel. The DS110DF410 also includes a five-tap Decision Feedback Equalizer (DFE) on each channel. The DS110DF410 can enhance the reach and robustness of long, lossy, crosstalk-impaired high speed serial links to achieve BER < 1×10-15. For less demanding applications/interconnects, the non-DFE variant DS110RT410 can be used to achieve the same BER performance. The two devices are pin-compatible. Each channel of the DS110RT410/DS110DF410 independently locks to serial data at data rates from 8.5 to 11.3 Gbps or to any supported submultiple of these data rates. A reference clock is not required, which simplifies system design and lowers overall cost. Both the DS110RT410/DS110DF410 support half-rate, quarter-rate and one-eighth-rate for backward compatibility. A protocol select mode is available to speed up lock time. Programmable transmit de-emphasis (up to -12 dB), transmit VOD (up to 1300 mVp-p) and adaptive receive equalization (up to 34 dB boost at 5 GHz) enable data transmission over lossy copper cables of typical lengths greater than 10 m or backplanes with multiple connectors and typical trace lengths greater than 40 inches. The CDR function is ideal for use in parallel optical modules to reset the jitter budget and retime high speed serial data. The programmable settings can be applied easily using the SMBus interface or they can be loaded via an external EEPROM. An on-chip eye monitor and a PRBS generator allow real-time measurement of high speed serial data for system bring-up or field tuning. The device is offered in a 48-pin LLP, 7 mm x 7 mm flowthrough package. Notice: This document is not a full datasheet.
